Kenneth Branagh's Thor was a superhero origin story wrapped in Shakespearean clothing, full of grandiose production design and canted camera angles. The theme of warring brothers dueling for their father's affection only reinforced the notion, with Chris Hemsworth playing the title character as a noble and stoic yet flawed hero.
The Dark World is rightfully regarded as one of, if not the, weakest entries in the entire Marvel Cinematic Universe. The franchise was in dire need of a fresh perspective, and Taika Waititi turned out to be an unlikely-yet-perfect fit for the material.
About as far away from Branagh's classic sensibilities as you could hope to get, Waititi re-energized the tiring God of Thunder by moving away from the opulence and borderline-pomposity of the previous two movies and into sheer batsh*t craziness.
In the space of just two movies, the Thor franchise had transformed from faux-Shakespearean drama into a wacky intergalactic buddy comedy packed full of witty one-liners and Jeff Goldblum going full Goldblum as an immortal alien. The biggest beneficiary of the drastic tonal change may have been Hemsworth himself, with Thor's reinvention into a cosmic frat-bro a much better fit for the actor than that of the troubled and reluctant hero.
I don't do social media, so like or follow me in person but please maintain a safe distance or the authorities will be notified. Don't snap me though, I'll probably break. I was once labelled a misogynist on this very site in a twenty paragraph-long rant for daring to speak ill of the Twilight franchise. I stand by what I said, it's crap.
